A paper authored by Huaiyuan "Ethan" Hu, Ashley Gilliam, and Fengrui Qu entitled, "Enolizable Ketones as Activators of Palladium(II) Precatalysts in Amine Arylation Reactions," has been published in ACS Catalysis. The paper describes a novel reduction of palladium(II) precatalysts using enolizable ketones.
A paper by Dr. Ethan Hu entitled, "Synthesis, Structural Characterization, and Coordination Chemistry of (Trineopentylphosphine)palladium(aryl)bromide Dimer Complexes ([(Np3P)Pd(Ar)Br]2)," was published in Inorganic Chemistry. Co-authors on the paper are, Monica Vasiliu, Deidra Gerlach, Fengrui Qu, Trent Stein, Dr. David Dixon, and Kevin Shaughnessy. The paper describes the structure of the trineopentylphosphine ligand in [(Np3P)Pd(Ar)Br]2 complexes as a function of the steric demand of the aryl group. The trineopentylphosphine is highly flexible allowing it to accommodate other sterically demanding ligands.
The Shaughnessy group presented 5 papers at the ACS meeting in New Orleans.
Kevin Shaughnessy gave a talk in the Homogeneous Catalysis for Applied Organic Synthesis symposium entitled, "Alkylphosphine cyclometallation as a mode of catalyst deactivation and a source of active catalysts."
Ethan Hu gave a talk entitled, "Methods to reduce Pd(II) precatalysts to Pd(0) for cross-coupling reactions" in the Organic Division.
Benjamin Headford presented a poster entitled, "Synthesis and catalytic application of asymmetrically substituted 1,3-diphosphines," in the Organic Division.
James Howard presented a talk entitled, "Synthesis and catalytic application of asymmetrically substituted 1,3-diphosphines," in the Division of Chemical Education.
Connar Franklin gave a poster in the Division of Chemical Education entitled, "Phosphine-free palladium catalysts for the direct arylation of heterocyclic aromatic compounds."
Congratulations to Huaiyuan "Ethan" Hu who successfully defended his dissertation entitled, "Part A: Arenepolythiols Synthesis And Doping Study Of Semiconducting Metal-Organic Framework; Part B: Mechanistic Study Of The Bis(Trineopentylphosphine)Palladium Catalyzed Buchwald-Hartwig Amination."
Write something about yourself. No need to be fancy, just an overview.
